You probably expected this, but Clayton Christensen—the Harvard professor who coined the term term that's become an almost religious byword in tech—is an arrogant ass. But in a new interview with Businessweek's Drake Bennett, you'll learn he's an even bigger ass that you ever imagined.

In the last years of the nineteen-eighties, I worked not at startups but at what might be called…

Still: the only name he seems more obsessed with than his own is Jill Lepore's, who he assumes a strange familiarity with:
